Buggy code:
public class HomeController { private static final Logger logger = Logger . getLogger ( HomeController . class . getName ( ) ) ; private static String STYLE_ITALIC = "italic" ; private static String STYLE_STRAIGHT = "straight" ; private static String HOTKEY_DISPLAY = "display" ; private static String HOTKEY_DONE = "display<seq2seq4repair_space>//done" ; private static String COLUMN_FIELD_CONTENT = "content" ; private static String COLUMN_FIELD_LABEL = "label" ; private static Label statusString ; private static ObservableList < Task > data ; private static CustomTextField customTextField ; @ FXML private TableView < Task > TaskTable ; @ FXML private TableColumn < Task , String > taskNameColumn ; @ FXML private TableColumn < Task , String > timeColumn ; @ FXML private TextField inputBox ; @ FXML private Label status ; private Gui gui ; public HomeController ( ) { } @ FXML private void initialize ( ) { } private void configureSettings ( ) { } private void disableDefaults ( ) { } private void configureTextField ( ) { } @ FXML private void configureStatus ( ) { } private void setFocusInputBox ( ) { } private void initialiseTableColumns ( ) { } private void initialiseTimeColumn ( ) { } private void initialiseTaskNameColumn ( ) { } EventHandler < KeyEvent > keyHandlers = new EventHandler < KeyEvent > ( ) { @ Override public void handle ( KeyEvent event ) { } } ; public String getAutocompleted ( String userInput ) { } public boolean getCommand ( String userInput ) { } public String getCmdHistory ( String direction ) { } public void displayStatus ( String receivedString ) { } private void handleF1Key ( ) { } private void handleF2Key ( ) { } private void handleF3Key ( ) { } public void handleOtherKeys ( KeyEvent event , KeyCode code ) { String userInput = new String ( ) ; if ( code . isLetterKey ( ) ) { userInput = ( HomeController . customTextField . getText ( ) ) + ( retrieveLetter ( code ) ) ; } else if ( code . equals ( KeyCode . BACK_SPACE ) ) { userInput = HomeController . customTextField . getText ( ) ; } else { return ; } String suggestedWords = getSuggestedWords ( userInput ) ; <START_BUG> HomeController . statusString . setText ( suggestedWords ) ; <END_BUG> HomeController . logger . finer ( suggestedWords . toString ( ) ) ; } private String getSuggestedWords ( String userInput ) { } private String retrieveLetter ( KeyCode code ) { } public void setMainApp ( Gui gui ) { } public void setData ( ) { } private void refreshTable ( ) { } private class TaskCell extends TableCell < Task , String > { public TaskCell ( ) { } @ Override protected void updateItem ( String item , boolean empty ) { } private void formatCellIfNotEmpty ( String item , TableCell < Task , String > tableCell ) { } private void formatCellText ( String item , TableCell < Task , String > tableCell ) throws ClassCastException { } private void setHeaderStyle ( ) { } private void setTextStyle ( ) { } private void setImportantStyle ( ) { } private void styleStraight ( ) { } private void styleItalic ( ) { } } private class TimeCell extends TableCell < Task , String > { public TimeCell ( ) { } @ Override public void updateItem ( String item , boolean empty ) { } } }

Fix:
displayStatus ( suggestedWords ) ;
